DnsResolver.resolve

bool resolve(scope  const(char)[]  hostname,  EventLoop.DnsWatcherCallback callback,  CancelToken cancel =  CancelToken
         .invalid)

@trusted

Asynchronously resolve a hostname.

Offloads getaddrinfo() to the thread pool provided at create(). The callback is invoked on the event loop thread when resolution completes (or fails).

Parameters

`hostname`	Hostname to resolve (e.g., "example.com").
`callback`	Invoked with results. Receives an empty address list and a `DnsError` on failure.
`cancel`	Optional cancellation token (via `CancelSource`).

Returns

true if resolution was queued successfully.

false if the pool is null, the loop is null, or no DNS slots are available.
